Once when he was an igumen, he attended a Divine Service in Constantinople where the Patriarchs of Antioch and Jerusalem served according to the Typikon of Saint Sabbas. He was impressed, and when he was elected archbishop he decided to translate this typikon into Serbian. This was the first complete typikon in the Serbian church. He was very dedicated to the cult of Saint Sava. Saint Nikodim was forced to with foreign heretics. As archbishop he coronated Saint Stefan Uroš III King of Serbia and the Coastlands on January 6, 1324. St. Nikodim explained in the prologue of his translation of Saint Sabbas' typikon that he wanted to continue work of St. Sava, who had introduced to the Serbian church the practice of the Church of Jerusalem. St Nikodim died on May 12, 1324.

He built the Church of Saint Demetrius in Pec Monastery. Nikodim was a good and capable hierarch. He was canonized in the last decade of the 14th century. Bishop Marko wrote a Service to Saint Nikodim honoring the saint.
